OK or NG
- OK: Mirror sensor LH circuit is OK.
- NG: GO TO 2.
CHECK HARNESS CONTINUITY 1
1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit and door mirror LH.
3. Check continuity between automatic drive positioner control unit connector 42 terminals 33, 41 and door mirror LH connector D4 terminals 4, 12.
  33 (W/L) - 4 (W/L): Continuity should exist.
  
  41 (Y/G) - 12 (LG): Continuity should exist.
4. Check continuity between driver seat control unit connector M42 terminals 33, 41 and ground.
  33 (W/L) - Ground: Continuity should not exist.
  
  41 (Y/G) - Ground: Continuity should not exist.
OK or NG
- OK: GO TO 3.
- NG: Repair or replace harness.

CHECK HARNESS CONTINUITY 2
1. Check continuity between automatic drive positioner control unit connector M41 terminals 6, 22 and door mirror LH connector D4 terminals 5, 11.
  6 (L/Y) - 5 (L/Y): Continuity should exist.
  
  22 (G/R) - 11 (G/R): Continuity should exist.
2. Check continuity between driver seat control unit connector M41 terminals 6, 22 and ground.
  6 (L/Y) - Ground: Continuity should not exist.
  
  22 (G/R) - Ground: Continuity should not exist.
OK or NG
- OK: Replace door mirror LH.
- NG: Repair or replace harness.
